+# mongoUrl
+
+A fork of node's `url` module, with the modification that commas and colons are 
+allowed in hostnames. While this results in a slightly incorrect parsed result, 
+as the hostname field for a mongodb should be an array of replica sets, it's 
+good enough to let us pull out and escape the auth portion of the URL.
